Increasing the ratio of renewable energy consumption is one way of reducing the harm to the environment by traditional sources of energy. At the same time on EU level common policies are developed in support of that goal. One of these policies is the Common Agricultural Policy. The EU provides co-funding for the construction of solar photovoltaics in rural regionsunder Measure “Support For Establishment and Development of Micro Enterprises”. Who can help us with funding to build solar panels? Banks? This is what I asked the EU. The way we produce the energy we need underlies our efforts to fight climate change. Fossil fuels still dominate the energy production sector. Their burning is a source of greenhouse gases. The use of Renewable Energy Sources, on the other hand, produces little or no greenhouse gas emissions at all. Every second the atmosphere of the Earth is reached by 1,35 kiloWatt-hour per square metre energy. In just a week the Sun provides us with more than we could acquire from all available energy reserves of the planet. I think that solar energy is the best source…How about wind?Why? Why do you prefer solar energy to wind and water energy?Because wind is not available all the time. Alright, you will install solar cells, but with what money? Where are you going to get it from? Could you save it?You will invest a lot, but the very solar collectors will bring returns by lowering your electricity bills. Solar panels covert sunrays into direct current electricity. As electric appliances in our homes use alternating current electricity, however, inverters are mounted on solar panels. They convert direct current into alternating one. Converted electricity goes to the main power controller. Thanks to a legal agreement between the users and the electric company, surplus electricity is fed into the grid. In the evening , when there is no daylight, the electricity company returns the spared energy back to the user. In other words, the electricity company functions like a huge battery. In terms of climate, Bulgaria ranks among the sunniest countries in the world. The number of sunny days in the different parts of the country range between 250 and 300 per year and in some areas they are even more than that. In Gotze Delchev, for instance, the number of sunny days per year is 317, in Smolyan – 315 and in Kardzhali – 309The average number of sunshine hours per year in Sofia is 2020 h, in Plovdiv – 2240 h and in Sandanski – 2520 h. Apart from providing us with light and heat, solar energy can be used for fun too. Small solar batteries can power little children’s toys like airplanes, boats and cars.
